CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Security Audits: Every contract undergoes internal review and formal verification before deployment.
- Compliance Ready: Built-in support for
ERC-20,ERC-721, and custom standards with upgradeability via proxies. - Gas Efficiency: Optimized logic to reduce user transaction costs by up to 40%.
- Full Lifecycle: From initial spec to mainnet deployment and post-launch monitoring.
Deploy a battle-tested, audited smart contract suite in 2-3 weeks, not months. We ensure your core logic is secure, efficient, and ready to scale.

PROVEN PROCESS
Our AI-Enhanced Audit Methodology
We combine deep protocol expertise with proprietary AI tooling to deliver comprehensive, high-confidence security assessments for your ZK-Rollup circuits and smart contracts.
01
Automated Vulnerability Detection
Our proprietary AI engine performs an initial scan, identifying common vulnerabilities and complex logical flaws in ZK circuits and Solidity contracts 10x faster than manual review alone.

SECURITY FIRST
Why a Unified ZK Stack Audit is Critical
A fragmented audit of your ZK-Rollup components creates dangerous blind spots. Our unified approach examines the entire system—circuits, contracts, and their integration—to eliminate systemic risks and ensure mathematical correctness.
03
Holistic Economic Security
We analyze the entire economic model—from circuit gas costs to contract slashing conditions—to identify vectors for griefing, MEV extraction, or protocol insolvency under edge cases.
04
Accelerate Mainnet Launch
A single, comprehensive audit report satisfies exchange and bridge integration requirements, providing the security assurance needed for partners and users to adopt your rollup.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process ensures security, gas efficiency, and upgradability from day one.
- Full Lifecycle Development: From initial design and
Solidity/Rustcoding to deployment and on-chain verification. - Security-First Approach: All contracts undergo internal audits and are built with
OpenZeppelinstandards and established security patterns. - Production Focus: We deliver gas-optimized code with clear documentation, enabling your team to iterate and maintain.
Move from concept to a live, audited mainnet contract in as little as 2-4 weeks.
Our engineers specialize in:
- Token Standards: Custom
ERC-20,ERC-721,ERC-1155, andERC-4626vaults. - DeFi Primitives: Automated Market Makers (AMMs), lending pools, staking mechanisms, and yield aggregators.
- Governance Systems: DAO frameworks, multi-sig wallets, and transparent voting modules.
- Cross-Chain Logic: Contracts designed for interoperability across
EVM-compatible networks and beyond.

ZK-Rollup Audit FAQs for Technical Leaders
Get answers to the most common technical and process questions from CTOs and engineering leads evaluating ZK-Rollup security audits.
We employ a hybrid methodology combining manual expert review with automated analysis. For circuits, we verify the soundness of the zero-knowledge proof system, check for arithmetic overflow/underflow, and validate constraint system logic. For smart contracts, we perform line-by-line Solidity/Vyper review, simulate adversarial scenarios, and test integration points. All audits follow a 4-phase process: Architecture Review, Automated Scanning, In-depth Manual Review, and Final Verification & Reporting.
